You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

I also have a Sony KDF 46E2000 that my husband purchased back in November 2006. It's now June, 2010 and for the past two years when I turn the television set on, at the botton left of the screen a box would pop up stating "Projection lamp life is ending, please replace bulb." (or something to that effect). I let it go because I didn't want to have to spend the $150- to buy a new lamp. Well, this morning it finally stopped working. So just as a little information, if you see this box pop up, you don't need to replace it right away. Like I said it was saying that for two years before it did anything. I love this television and it's the only issue we have had with it. I like the fact that the bulb is very easy to replace. Maybe we got lucky and got one of the better tv's since it has lasted us almost four years before having to replace the bulb?

more than likely fuse is gone in plug. take dish washer out. change fuse in plug. if it doesnt work get extension lead and run it from a socket that definatly does work and plug washer into that. if nothing then its internal.

unplug the unit for 24 hours and try it again. if the unit doesnt come on at all, even after that, then the internal fuse is blown, or a power spike / surge has friend part of the internal power supply. you'll have the go through the warranty process of the manufacturer, or find a local tv repair shop.

ok , on hitachi pro tv is very common with bad power supply u may want to replace the voltage regulator which is next to the fuse u already replace , also loose connection on all the power supply seccion , also u may want to check the resistor close by the convergence ic 2.2 ohn if this are smoke replace stk392-110

ticking sound (like a Watch) coming from around the Flyback Transformer but I don't see a spark is called EHT voltage .
if eht voltage is ok
1 check filament is glowing or not if it is ok check voltages on crt.
2 if it is ok check luminance section in chroma section.
if filament is not glowing check for low eht due to hor section
check power supply output also.
good luck
